Abstract
Abstract A gymnastic apparatus comprises a base, a treading member, a handle rod, a seat rod, a first linking member, and a second linking member. The base has a support frame mounted thereon. The treading member has a rotary shaft pivoted to the support frame, two pedal rods fastened respectively to both ends of the rotary shaft, and two pedals pivoted respectively to the free ends of the two pedal rods. The handle rod is provided at the top end thereof with two hand grips and pivoted at the bottom end thereof to the base. The seat rod is pivoted at the bottom end thereof to the base and is provided at the top end thereof with a seat cushion. The first linking member is disposed between the rotary shaft of the treading member and the handle rod such that the rotational motion of the rotary shaft is caused to link with the angular displacement motion of the handle rod. The second linking member is located between the handle rod and the seat rod such that the handle rod is caused to link with the angular displacement motion of the seat rod.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
248 words
A gymnastic apparatus capable of animating a horse riding and comprising: a base having a front end provided with a support frame fastened thereto; a treading member provided with two pedals and pivoted to said support frame; a handle rod pivoted to said base; a seat rod pivoted to said base and located behind said handle rod, said seat rod having a seat cushion fastened thereto; and a plurality of linking members for transmitting motion among said treading member, said handle rod and said seat rod; wherein said treading member has a rotary shaft pivoted to said support frame, two pedal rods fastened respectively to both ends of said rotary shaft, and two pedals fastened respectively to two free ends of said two pedal rods; and wherein said linking members include a first linking member and a second linking member, with said first linking member being located between said rotary shaft of said treading member and said handle rod for linking a rotational motion of said rotary shaft with an angular displacement motion of said handle rod, and with said second linking member being mounted on said base or said support frame such that two extension ends of said second linking member are connected respectively with said handle rod and said seat rod for linking an angular displacement motion of said handle rod with an angular displacement motion of said seat rod, said two extension ends of said second linking member capable of bringing about a reverse motion.
Claim 2
Dependent Claim
248 words
A gymnastic apparatus capable of animating a horse riding and comprising: a base having a front end provided with a support frame fastened thereto; a treading member provided with two pedals and pivoted to said support frame; a handle rod pivoted to said base; a seat rod pivoted to said base and located behind said handle rod, said seat rod having a seat cushion fastened thereto; and a plurality of linking members for transmitting motion among said treading member, said handle rod and said seat rod; wherein said treading member has a rotary shaft pivoted to said support frame, two pedal rods fastened respectively to both ends of said rotary shaft, and two pedals fastened respectively to two free ends of said two pedal rods; and wherein said linking members include a first linking member and a second linking member, with said first linking member being located between said rotary shaft of said treading member and said handle rod for linking a rotational motion of said rotary shaft with an angular displacement motion of said handle rod, and with said second linking member being mounted on said base or said support frame such that two extension ends of said second linking member are connected respectively with said handle rod and said seat rod for linking an angular displacement motion of said handle rod with an angular displacement motion of said seat rod, said two extension ends of said second linking member capable of bringing about a reverse motion.
Claim 3
Dependent Claim
